I've been struggling with this for going on a week now and tried just about just about every iteration I could find referenced on searches.
I'm trying to integrate google charts into this program to create three charts based on different data content.
There is no event other than onload that I can determine. Can someone please review and advise how/why the js functions are not triggering?
Thanks

I know the code is not the prettiest - but I'm just trying to get it functioning.
Any pointers greatly appreciates. Thanks cyclops

What kind of JS errors are you seeing in your browser's console? (F12)

Oops - forgot to include those. Right now its only the following:

Uncaught SyntaxError: Unexpected token :
and the returned content from the server is:
{"2015":["1":130,"2":124,"3":156,"4":173,"5":180,"6":189,"7":174,"8":137,"9":133,"10":157,"11":141,"12":145],"2016":["1":180,"2":174,"3":230,"4":228,"5":223,"6":222,"7":223,"8":197,"9":156,"10":186,"11":157,"12":182],"2017":["1":207,"2":175,"3":291,"4":254,"5":245,"6":284,"7":191,"8":201,"9":141,"10":114,"11":69,"12":39]}

I've tried so many different ways to convert this string into a javascript array.

Seems like you are serializing the array from PHP. Have you tried to instead use json_encode() to turn into something Javascript can read?

Thanks for the reply. Believe it or not the return statement reads:

return json_encode($aray_name);

I'm surprised that this json looks a little different than others I've done. Perhaps because its a multi-dimensional array???

I think your error has nothing to do with your JSON. It lies a bit further down in the chart options:


Code: 
// Define Display Options
var options = {
title: 'Procedures Performed by Month & Year\n\n',
hAxis: { title: 'by Month', titleTextStyle: {color: '#333'}},
vAxis: { title: 'Count', minValue: 0},
[b]width: { 120, height: 60}[/b]
};

Should be:
Code: 
...
[b]width:120, 
height: 60[/b]
};

Thanks for picking that up. Often times in the myriad of detail we miss the small stuff.
The actually issue turned out to be a strange one. Even though the encoded json string was returned from PHP
the javascript had to further stringify each character of the JSON object. Each character, in turn, was run through
toString back to itself and then the charting took it without issue.
Thanks for responding though. I'd been struggling with this for many,many days and just resolved it about an hour ago.
